New description: [New technical field] This creation is related to the shape of the blade frame, especially the leaf-type leaf year body, which includes a - joint - extension and a second connecting portion, wherein the second portion of the extending portion is located between the first (four) and the second folded corner and is formed toward one side of the turntable - from the two sides to the middle portion - the concave curved surface, Increase the strength of the extension. [Previous technology] Please refer to the figure in the sixth figure. Press, the blade frame (worker) of the general ceiling fan is mainly used for the blade connection of the ceiling fan. The blade frame (i(10)) of the (4) is made of zinc. The body-body molding, the body extension includes a first connection portion (ii), an extension portion (work 02), and a second connection portion (103), the first connection portion (1〇1) is available a circular turntable connection of the ceiling fan motor, the second connecting portion (the work 3) is connectable to the blade of the book fan, so that the blade can be lapped and fixed on the turntable via the leaf frame body (i 〇〇); However, as the international price of zinc continues to rise, coupled with the blade frame made of re-casting of the material, (1 0 0) has the advantages of easy embrittlement, thicker, heavier and more difficult to break. Missing. In view of this, the industry in the same field has developed a "iron plate stamping type ceiling fan #片架" made of a relatively inexpensive and structurally stronger iron piece, such as the Republic of China Patent Gazette G5268. The blade frame-body extension includes a first connection portion, an extension portion 2 and a second connection portion. The first connection portion is connectable to a turntable of the ceiling fan motor, and the connection portion is connected to the ceiling fan. The improvement is that the #_protrusion is provided at the position where the blade screw is locked, and the threaded hole is provided at the center of the leakage convex _. M329113 - The optimal structure: the price is low, "light, thin and lose" _, etc. are all flat materials, and the red light Wei's connection. The concave butterfly 峨 fine coffee axis · Shape butterfly =::^=== (10) to prevent the thickness of the blade frame compared to the reed material The reason is thin, therefore, the fold is now: the weight of the long-term branch blade plus the centrifugal force generated by the rotation of the motor, and the occurrence of Φ, the tender willow magnetic, followed by the motor, the machine plus the 'four (4) structure is indeed There is a need for further improvement and reinforcement. The reason is that the subject of this creation is to be solved. In order to improve the above-mentioned conventional structure, the cost is too high and the strength is not good, and the first sound of the patent (10) is poor. The lack of such a situation, therefore, the creator is actively researching, and after painstaking development, finally developed a practical work that has practical effects. [New content] 'The main purpose of this creation is to provide - the type _ iron sheet to - The blade β' made by the body stamping method not only avoids the occurrence of deformation and distortion at the corner of the blade frame, but also has a sheet-like ceiling fan blade frame with low material cost, better structural strength and better workability. In order to achieve the above-mentioned effects, the technical means adopted by the present invention is that it is made of a one-piece stamping method of iron sheets, and that it has a - joint portion, an extension portion and a second joint portion. - the connection is available for connection with the crane, the M329113
